Incidentally, the very nice schematic of cryosphere changes over both ice sheets was drawn by @jmalumbresolarte.bsky.social Tak! 🙏

New paper out today in @nature Geosciences:
The Greenlandification of Antarctica

The Greenlandification of Antarctica | Nature Geoscience
Climate and ice sheet processes in Antarctica increasingly reflect those observed earlier in Greenland. Applying process insights from Greenland can improve projections of future Antarctic ice and climate behaviour.

Following @jonathanwille.bsky.social 's recent post about an #atmosphericriver / #heatwave in West Antarctica, I did some digging in ERA5 to look at the drivers and impacts of the event. Sharing here for those who might be interested 🌨️🌡️👀

In today’s climate, #atmosphericrivers play a major role in bringing snowfall to #Antarctica. Have you ever wondered how that might change in the future?

Out today, our new study on the future frequency and precipitation impacts of Antarctic atmospheric rivers:

Rising atmospheric moisture escalates the future impact of atmospheric rivers in the Antarctic climate system - Communications Earth & Environment
Antarctic atmospheric rivers are projected to double in frequency and cause 2.5 times more precipitation by 2066–2100 due to rising atmospheric moisture, according to large ensemble climate simulation...

Huge congrats to @drgilbz.bsky.social for producing a unique, localized study of extreme precip in West Antarctica!! 🇦🇶 This study highlights what we miss when we rely on reanalyses to assess extreme events - and the role of steep terrain in the mesoscale meteorology of the Amundsen Sea Embayment 🌧️

Stoked to see this awesome Antarctic atmospheric river review paper in print! ☃️ Many thanks to @jonathanwille.bsky.social for leading the effort and to the co-authors, who were a great team to be a part of 🦭 Excited to promote this fantastic new resource!
🧵 1/4 I'm very happy to share this comprehensive review paper covering atmospheric rivers in Antarctica. It was an idea that started during a workshop in Boulder back in summer 2023 and now is finally published thanks to an amazing team effort rdcu.be/d9nFY.
